The ATU, a dying art?

Because of the increase of domestic interference, the use of endfed antennas - fed at the shack (house) end - is now definitely a 'bad thing', whereas a remote feed usually results in fewer interference problems. My inverted L is matched at the base of the vertical section at the bottom of the garden. I use an AAMU that works from 160m to 6m, it's battery powered with the latter being charged by a solar cell panel. Now, I could easily make a matching unit from discrete components and remotely control adjustment, by wireless or wire. I could use RF sensing to drive a controller. Or I could let the AAMU take the strain so I can spend my precious spare time doing radio stuff that really interests me - like SDR. I also enjoy spending time in the company of friends and wife. -- M0WYM Sales @ radiowymsey http://stores.ebay.co.uk/Sales-At-Radio-Wymsey/ http://sales-at-radio-wymsey.ebid.net/ |
